Monitoring the lifecycle of tiny catalyst nanoparticles Bochum, Germany (SPX) May 07, 2019 Nanoparticles can be used in many ways as catalysts. To be able to tailor them in such a way that they can catalyse certain reactions selectively and efficiently, researchers need to determine the properties of single particles as precisely as possible. So far, an ensemble of many nanoparticles is analysed. However, the problem of these investigations is that the contributions of different parti Source: NanoDaily.com http://www.nanodaily.com/reports/Monitoring_the_lifecycle_of_tiny_catalyst_nanoparticles_999.html

Harnessing microorganisms for smart microsystems Toyohashi, Japan (SPX) Apr 16, 2019 A research team at the Department of Mechanical Engineering at Toyohashi University of Technology has developed a method to construct a biohybrid system that incorporates Vorticella microorganisms. The method allows movable structures to be formed in a microchannel and combined with Vorticella. In addition, the biohybrid system demonstrates the conversion of motion from linear motion to ro Source: NanoDaily.com http://www.nanodaily.com/reports/Harnessing_microorganisms_for_smart_microsystems_999.html

Quantum optical cooling of nanoparticles Vienna, Austria (SPX) Apr 03, 2019 Tightly focused laser beams can act as optical “tweezers” to trap and manipulate tiny objects, from glass particles to living cells. The development of this method has earned Arthur Ashkin the last years Nobel prize in physics. While most experiments thus far have been carried out in air or liquid, there is an increasing interest for using optical tweezers to trap objects in ultra-high vac Source: NanoDaily.com http://www.nanodaily.com/reports/Quantum_optical_cooling_of_nanoparticles_999.html

Defects help nanomaterial soak up more pollutant in less time Houston TX (SPX) Mar 14, 2019 Cleaning pollutants from water with a defective filter sounds like a non-starter, but a recent study by chemical engineers at Rice University found that the right-sized defects helped a molecular sieve soak up more perfluorooctanesulfonic acid (PFOS) in less time. In a study in the American Chemical Society journal ACS Sustainable Chemistry and Engineering, Rice University researchers Mich Source: NanoDaily.com http://www.nanodaily.com/reports/Defects_help_nanomaterial_soak_up_more_pollutant_in_less_time_999.html

Researchers report new light-activated micro pump Houston TX (SPX) Mar 15, 2019 Even the smallest mechanical pumps have limitations, from the complex microfabrication techniques required to make them to the fact that there are limits on how small they can be. Researchers have announced a potential solution – a laser-driven photoacoustic microfluidic pump, capable of moving fluids in any direction without moving parts or electrical contacts. The work is described in th Source: NanoDaily.com http://www.nanodaily.com/reports/Researchers_report_new_light_activated_micro_pump_999.html

The holy grail of nanowire production Lausanne, Switzerland (SPX) Feb 25, 2019 Nanowires have the potential to revolutionize the technology around us. Measuring just 5-100 nanometers in diameter (a nanometer is a millionth of a millimeter), these tiny, needle-shaped crystalline structures can alter how electricity or light passes through them. They can emit, concentrate and absorb light and could therefore be used to add optical functionalities to electronic chips.

Nano drops a million times smaller than a teardrop explodes 19th century theory Warwick UK (SPX) Feb 13, 2019 Droplets emanating from a molecular “nano-tap” would behave very differently from those from a household tap 1 million times larger – researchers at the University of Warwick have found. This is potentially crucial step for a number of emerging nano technologies, e.g., manufacture of nano-sized drug particles, lab-on-chip devices for in situ diagnostics, and 3D printers capable of nanoscale reso Source: NanoDaily.com http://www.nanodaily.com/reports/Nano_drops_a_million_times_smaller_than_a_teardrop_explodes_19th_century_theory_999.html
